Reasons buyers look elsewhere
- OpenText offers a broad cybersecurity suite covering areas like endpoint security, email protection, and threat intelligence. Some organizations prefer specialized solutions focused on a single security domain (such as SIEM, endpoint protection, or identity security) that may provide deeper capabilities in that specific area.
- Companies that rely heavily on modern DevOps tools, cloud platforms, or custom security stacks may prefer alternatives offering broader integration ecosystems or open API environments to build customized security workflows.
- Enterprise cybersecurity platforms often involve higher licensing costs, implementation expenses, and long-term contracts. Smaller organizations or MSPs may evaluate competing tools that provide lower subscription costs or flexible pricing models suited for smaller teams.
